Presenteeism at Leadership Level: The Hidden Cost Nobody Measures

Presenteeism is working while unwell: physically present, operating at a fraction of normal capacity. It is the counterpart to absenteeism, and it costs most organisations considerably more, for the simple reason that nothing about it announces itself.

Absence is visible. Someone is not at their desk. Their work is not getting done. Their direct reports are escalating to the next level up. The cost announces itself.

Presenteeism is invisible. The person is at their desk. They are answering emails. They are attending meetings. They look present. And they are operating at a fraction of their capacity, making decisions they will have to revisit, missing signals they would normally catch, draining energy from teams who sense something is wrong but cannot name it. The cost accumulates silently, and it dwarfs absence.

The Health and Safety Executive recorded 964,000 workers with stress, depression or anxiety caused or made worse by work in 2024/25, and 22.1 million working days lost to it, at an average of 22.9 days per case. Two years earlier the same figures were 875,000 workers and 17.1 million days, so the direction is not in question.

Those are the visible numbers, counting the days people were too unwell to work at all. The invisible number, the days people worked while unwell, is substantially larger and almost entirely unmeasured.

What Presenteeism Costs UK Employers

The cost is not a matter of inference. Deloitte’s 2024 mental health and employers report puts the annual cost of poor mental health to UK employers at £51 billion, down from £56 billion in 2021 and up from £45 billion in 2019.

Of that total, Deloitte identifies presenteeism as the largest single contributor, at around £24 billion a year, describing it as “where people work in spite of illness and not perform at their full ability”.

That figure deserves to be read slowly by anyone who receives an absence report. The most expensive component of presenteeism in the UK, and of workplace ill-health generally, is not the people who stay at home. It is the people who come in. And it is the one component that appears in no management report, has no owner, and triggers no policy.

What Presenteeism Means

The word carries a specific meaning in occupational health, and it is worth being exact about it, because the everyday reading of “presence” points the wrong way.

Presenteeism does not mean showing up. It means showing up when you should not have, or when you are in no state to do the work properly, and it covers physical and mental health alike. Someone coming to work through a chest infection is the obvious case. So is someone who has not slept properly in three months, someone recovering from a bereavement, and someone whose attention is entirely occupied by a situation at home. In each case attendance is complete and capacity is not.

The defining feature is the gap between attendance and capability. Attendance is recorded; capability is not. Every system an organisation uses to track its people, from the HR record to the absence report to the door pass, measures the first and is structurally blind to the second. That is not a failure of diligence. It is what those systems were built to count.

For knowledge workers and leaders, whose output is decision quality rather than units produced, the gap is where organisations lose most of the value. A production line reveals reduced capacity within hours. A boardroom can absorb it for years.

Absenteeism and Presenteeism: The Difference

Absenteeism and presenteeism are usually discussed together and are frequently confused, so the distinction is worth setting out plainly.

The relationship between them is the part boards tend to get wrong. They are usually treated as opposites, so that falling absence reads as improving health. Often it is the reverse.

Some organisations make taking sick leave difficult, through attendance targets, aggressive return-to-work processes, or simply a culture in which nobody senior is ever off. In those places absence figures fall and presenteeism rises. The work does not get done any better. It gets done worse, by people who are unwell, and the reporting improves. An unusually low absence rate in a demanding organisation is a finding that warrants investigation, not a result worth celebrating.

This is the same measurement problem examined from the other side in the sickness absence iceberg: the costs that are easy to count are the smaller ones, and the reported figure is misleading rather than merely incomplete.

Why People Work While Unwell

Presenteeism is rarely irrational. In most organisations it is the sensible response to the incentives on offer, which is why exhortation does not fix it.

Sick pay does not replace income. Statutory Sick Pay is £123.25 a week for up to 28 weeks. For anyone without generous occupational cover, a week of illness is a week of serious financial loss, and the arithmetic argues for going in.

Nobody covers the work. Where a role has no deputy and no slack, absence does not remove the work. It postpones it, and adds the cost of returning to a backlog. Taking two sick days to recover properly means four days of catching up, so people take none and recover slowly at their desk instead.

Job security feels contingent. In a restructure, during a probation period, or on a fixed-term contract, being seen to be reliable outranks being well. Attendance is legible to an employer in a way that quality is not.

The workplace culture is set from the top. Where the senior team works through illness, answers email on annual leave and treats stamina as a virtue, the rest of the organisation reads the standard accurately and meets it.

The first three are structural and can be designed out. The fourth cannot be delegated, which is the subject of the closing section.

The Signs of Presenteeism

Because presenteeism generates no report, it has to be recognised behaviourally. The common indicators, all of them observable without a survey:

• Attendance that is unusually perfect, particularly from someone managing a known health condition, or in a team under sustained pressure or in an organisation with a demanding attendance policy
• Work being delivered on time but needing more revision than it used to
• Longer hours producing less output, with the extra time absorbed by tasks that used to take an hour
• Withdrawal from the discretionary parts of the job: the contributions in meetings, the mentoring, the reading, the things nobody chases
• Decisions being deferred, or defaulting to the familiar option, where the same person would previously have pushed
• Irritability and a shortening fuse in someone whose temperament had been steady

None is conclusive alone. A cluster of them in a capable person is the pattern, and it usually predates any formal sign of a problem by months.

Remote Work Made It Harder to See

Working from home removed the last physical check on presenteeism. Nobody sees the person who looks unwell, so the only signal an organisation receives is activity: messages sent, meetings attended, the status indicator showing green.

Employers have noticed. In the CIPD’s Health and Wellbeing at Work 2025 survey, 35% of organisations reported that presenteeism had risen as a result of employees working from home.

That inverts the problem. Somebody genuinely too ill to work now has fewer reasons not to log on, because attending costs nothing but opening a laptop, and visible availability has become the proxy for contribution. The result is a longer tail of reduced productivity that no absence system records and no manager observes.

For senior people the effect is stronger still, because their work was always mostly judgement and conversation, and both can be performed adequately enough to pass while the quality quietly degrades.

Why It Is Uniquely Dangerous at the Top

At leadership level, presenteeism is uniquely dangerous. When a frontline employee works while unwell, the cost is primarily their own reduced productivity. When a director or senior executive works while unwell, the cost compounds through every decision they make and every interaction they have. A stressed, depleted leader makes worse strategic judgments. They are more likely to default to familiar options rather than creative ones. They are more susceptible to cognitive biases, confirmation bias, loss aversion, short-termism. They are more likely to snap at colleagues, erode psychological safety, and model the kind of unsustainable behaviour that cascades through the organisation. One senior leader operating at sixty percent capacity because they refuse to stop does more damage than ten absent employees.

There is also nobody positioned to intervene. A struggling team member has a line manager whose job includes noticing. A struggling chief executive has a board that meets six times a year and a leadership team who report to them. The higher the role, the fewer the people with both the standing and the safety to say something, which is the subject of loneliness at the top.

A Textbook Case

During his own burnout in a high-pressure banking environment, Craig Fearn was the textbook case of leadership presenteeism. He was in the office. He was in the meetings. He was making decisions. And he was doing none of it well. The most dangerous part was that he did not realise how compromised his judgment had become, because the deterioration was gradual, and because nobody around him felt able to say anything. When someone at your level is struggling, the unspoken calculation among colleagues is often “not my place” or “they will sort it out” or “I do not want to be the one who raises it.” So the leader continues, the quality of their work degrades incrementally, and the organisation absorbs the cost without ever measuring it.

The World Economic Forum has identified mental health and wellbeing as a critical workforce risk in its Global Risks Report, noting that the economic cost of mental ill-health is projected to reach $6 trillion globally by 2030. A significant proportion of that cost is presenteeism, the productivity lost while people are physically present but mentally absent. At senior level that loss is almost impossible to see from outside, because the work leaves no visible trace of the capacity it was done with.

Measure What Happens, Not What Is Reported

From work with senior leaders across multiple sectors, the organisations that take presenteeism seriously are the ones that measure what is actually happening rather than what is reported. They look at discretionary effort, are people going above and beyond, or are they doing the minimum required to maintain the appearance of performance? They look at decision velocity, is the organisation making decisions at its normal pace, or has everything slowed down because key people are operating below capacity? They look at interpersonal friction, is there an unexplained increase in conflict, complaints, or grievances that might trace back to stressed leaders creating stressed teams? These are leading indicators of presenteeism that most organisations never track.

Reducing Presenteeism

Three structural levers, in the order they tend to work:

Make recovery affordable. Paid sick leave above the statutory floor removes the financial argument for coming to work unwell. It is the single change that alters behaviour fastest, because it is the only one that changes the arithmetic instead of the messaging.

Make absence survivable. Cross-cover, a named deputy for every critical role, and enough slack in workload planning that two days off does not create four days of backlog. Where absence is genuinely absorbable, people take it early and briefly instead of late and at length.

Stop rewarding attendance. Perfect-attendance recognition, absence thresholds applied without discretion, and return-to-work processes designed to deter instead of support all raise presenteeism while improving the figures. An organisation that measures only absence will get less absence, and it will not get a healthier workforce.

None of these is a wellbeing programme, which is the point. Presenteeism responds to sick pay, cover and workload, and it is largely indifferent to mindfulness apps.

The Solution Starts at the Top

The solution starts with modelling. If the CEO works through illness, never takes holiday, and sends emails at midnight, the organisation learns that this is what success looks like. Senior leaders set the norm. The most effective intervention is remarkably simple: leaders who visibly take care of themselves, who take their leave, who leave at a reasonable hour, who say “I am not at my best today”, give permission for everyone else to do the same. That is not weakness. It is the most practical form of risk management available to any board.

For organisations ready to address the hidden costs of presenteeism, resilience assessment can surface the data that traditional absence reporting misses. And for boards who want to understand the full financial picture, organisational resilience frameworks connect leadership wellbeing directly to organisational performance.
